Ottawa River Watershed

Scenario 3 - Consequences of Watershed Growth Over Time


Scenario 3

Growth Controls

Growth controls in addition to mitigation efforts implemented in the Ottawa River watershed succeed in retaining the current water quality status of most sections in the watershed. Additional growth regulations significantly reduce the adverse affects of urbanization. The investigated areas of the watershed remain in their current status for 40 years. Only one portion of the area is affected in year 50 and is reduced from poor to very poor. With the exception of year 50, where cumulative impacts are now evident, growth controls and mitigation efforts have greatly assisted in keeping additional degradation in check throughout much of the forecasted time frame.
